Uniross ML2032 Lithium Rechargeable Coin Cell Battery | Industrial Bulk Supply

Model No: ML2032

Uniross ML2032 lithium-aluminium rechargeable coin cells deliver 65 mAh at 3V in a 20.0mm diameter, 3.2mm profile — the highest-capacity and highest-cycle cell in the 20mm ML range. With 600 cycles at 10% DOD and 300 cycles at 20% DOD, the ML2032 is the standard specification for rechargeable 20mm coin cell applications where both energy reserve and long cycle life are engineering priorities. Used in industrial embedded systems, CMOS/RTC backup, electronic shelf labels, and any OEM design with a 20mm rechargeable coin cell socket and an integral charging circuit. Available in bulk from European stock.

Product Features

  • 600 cycles at 10% DOD — highest cycle rating in the 20mm ML series — supports multi-year rechargeable service life in OEM products with integral charging; 600-cycle rated cells deployed at one cycle per day deliver over 1.6 years of daily cycling before reaching rated end-of-life — significantly longer for less frequent cycling regimes
  • 65 mAh — maximum energy in the 20mm rechargeable format — largest capacity available in a 20mm lithium coin cell; extends backup duration and reduces the frequency of charge events in low-average-current embedded systems
  • Direct rechargeable replacement for CR2032 footprint designs — 20.0×3.2mm dimensions are dimensionally identical to the most widely used primary coin cell; enables rechargeable upgrade without PCB or housing redesign for systems with a charging circuit
  • -20°C to +60°C operating range — cycle count and capacity retention verified across the full industrial temperature range; suitable for outdoor infrastructure, transportation, and industrial control environments
  • IEC 60086 & RoHS compliant — EU and UK market qualified; applicable to industrial automation, medical device, smart building, and cellular IoT OEM supply chains
